Hi all. I just changed the oil in wife's Santa Fe. I cut open the Bosch 3312 I took off and it looked fine.....but.....I found a couple of small pieces of filter material (about the size of a Nickle) in the bottom of the can. It was dusk at the time, but I will take pics tomorrow. Very strange, I looked at filter very closely and it all the media is in good shape, no tears. Even at the seam. Maybe when the filter gets cut and crimped, the excess fell in the can? I'm not sure. What if a piece had gotten into my engine? Scary implications.....
